Described are methods and systems for processing data. A motion estimator uses a block of an input frame of video data and a block of a reference frame of video data to generate motion vectors according to a first encoding scheme. A motion compensator produces half pel motion vectors from the motion vectors according to a second encoding scheme that is different from the first encoding scheme.
